摘　　要：社交问答用户的信息行为受多种因素影响,本文旨在探究社会资本与用户问答行为的关系。本研究应用林南社会资本理论框架和厄普霍夫对社会资本的分类,对用户问答行为依用户角色(社区成员、提问者、回答者)进行分析。数据集包括1 952名用户、176个问题、2 133个回答。结果表明:用户内容性的贡献度主要与认知性线上自致资本相关,互动性的贡献度与结构性线上自致资本相关;用户提问获得的响应与其社会资本无关,回答获得的响应与社会资本关联较弱;线上自致资本较高的回答者的答案被选为精华答案的比例更高。用户认知性、结构性线上自致资本的积累均基于其参与内容性、互动性活动的数量,但自致资本并不会显著影响用户提问或回答获得的关注。Users＇ social question-answering behavior may be influenced by several factors. This article aims to understand the relationship between social capital and social Q＆A behavior. We applied Lin＇s Social Capital Theory and Uphoff＇ s categorization of different types of social capital to analyze users＇ social Q＆A behavior based on user roles ： community member, questioner, and answerer. The data set con- tained 1952 user profiles, 176 questions, and 2133 answers. It is found that：Content-based contributions correlate with cognitive social capital and structural social capital, whereas social contributions correlate with structural social capital ;The number of answers a questioner receives have no correlation with his or her social capital status, and the responses （number of ＂ votes＂ ） an answerer receives correlate weakly with the person＇s social capital;Archived ＂high-quality＂ answers are mostly from users with higher social capital. The accumula- tion of both of cognitive and structural self-made social capital is correlated to the amount of content-based and social contributions to the Q＆A community. Self-made social capital seems to help the answers to receive more ＂Votes＂ slightly, but does not seem to help the users to attract more responses to their questions.
